After upgrading to V5.01, there is no sound on previous vpj files created. When opening the project files, the following error displays "One or more sound clips on your sequence is still processing. You will not hear these clips until processing finishes." However the processing never ends. I can hear the audio clip in the "clip preview" but when I play a "sequence preview" or a "preview" there is no sound just the error message. If I start a new project and save it, everything works fine. One suggestion was to clear the cache files but that did not correct the error. I would appreciate any suggestions to resolve the problem?
